control over move behavior

I'm using move behaviors to fly a camera over still photographs in 3D space. the behavior tab in the inspector gives you numerical control over x and Y position of the move, but not Z. Is there any other tab that allows you to adjust position other than just dragging on the arrows on the camera itself?

Also, sometimes I find that the x/y/z control arrows are far outside the frame even if I go to 12% view in the active camera window. Any tricks for keeping it visible?
